BenJilks 1c27568ab0 PixelPaint: Undo and redo actions ...

The most used feature of any image editor, undo. Each tool now
notifies the ImageEditor that they completed an action, where
it'll take a snapshot if its current state.

For now, a snapshot is just a copy of the whole image and its
layers. There's a hard limit on the amount of actions it stores.
